This. There was a lot of hyperbole with the Sky launch and Brailsford's bold prediction, and then Wiggins' sudden emergence as a GT contender in 2009, and British gold medalist, Sky had to have him as their poster boy. As has been pointed out, they did have other riders pencilled in as potential winners they were looking to develop, but in Brad they had a ready-made one.
Wiggins departure from Garmin may have been acrimonious, but it made perfect sense to join Sky; from a competitive angle, from a commercial angle, from a financial angle. I'm not saying Sky were any better equipped than Garmin at the time, but to claim Bradley's motivation for joining Sky to win a GT is a lie is nuts really. And look, he did.
